Looking at a 99 F250 XLT extended cab, 5 speed manual 2WD with the 7.3 Powerstroke diesel. 97k miles. Not too familiar with these. It has a chip...not sure which one. Also a Banks turbo back exhaust. Pics look very good. Any major pitfalls to look out for? What are the questions I need to ask here? Price is around 12k. Will be looking at it this Sunday. (8/19) Thanks!
